I would not use zinc plated hardware outdoors unless you have no other
option. You can buy galvanized u-bolts and nuts or stainless steel ones at
a number of places such as MSC Direct or McMaster Carr. For my homebrew
antennas I use 100% stainless steel hardware. Even the antennas that were
subject to a real salt spray test in Aruba were easy to disassemble. DX
Engineering sells a nice u-bolt / saddle kit.

Subject:[TowerTalk] Force 12 Hardware Question
From:Gerard Jendraszkiewicz <jend@uchicago.edu>

Hello Everyone,
My Force 12 5BA is currently down to replace a broken truss wire. I also
plan to replace the boom to mast plate. The one I had was a the older
'small' style.
Now this brings me to the question.
The U-Bolts that hold the elements to boom appear quite rusty, although it
appears to be just surface rust. The nuts all look to be in good shape. Is
there any thoughts to replacing the u-bolts ? The replacements I have
obtained from Force 12 are the same Zinc plated type that were OEM on the
antenna.
I also have new insulators, but again the old insulators look just fine,
they are a bit weathered but seem to be in good shape. Replace or not to
replace ?
The antenna has been up for about 10 years and is a very good performer. Any
thoughts ? I think all the old u-bolts would have to be cut off for
replacement.
Comments ?
Thanks
Jerry, KE9I
